7.49.1
स॒मु॒द्रज्ये॑ष्ठाः सलि॒लस्य॒ मध्या॑त्पुना॒ना य॒न्त्यनि॑विशमानाः | इन्द्रो॒ या व॒ज्री वृ॑ष॒भो र॒राद॒ ता आपो॑ दे॒वीरि॒ह माम॑वन्तु ||
FORTH from the middle of the flood the Waters-their chief the Sea-flow cleansing, never sleeping. Indra, the Bull, the Thunderer, dug their channels: here let those Waters, Goddesses, protect me.
